Nymph is a rare Pre-Hardmode enemy that spawns underground. It is arguably the rarest enemy in Terraria.
When first spawned, the nymph appears as the Lost Girl, an NPC, but when approached, it transforms into a Nymph. Please note that this will only take place the first time the player encounters the Nymph, and afterwards it will spawn as Nymphs.
- Nymphs are more common in the Mobile Version than PC.
